UK Man "Foils" Ghosts http://www.findarticles.com Current Science, Jan 19, 2001 Ghosts Busted in Haunted Rooms "Vic Tandy, a computer expert, was working late one night in a laboratory in Warwick, England, which had a history of being haunted. At one point, a cold sweat and a feeling of depression overcame Tandy. Then a blurry gray figure appeared out of the corner of his eye. As he turned to the ghostly figure, it disappeared! By coincidence, Tandy, who is a fencing enthusiast, took his fencing foils to the lab with him the next day. He clamped the blade of one foil in a vise in order to oil it. Returning with the oil, he found the blade vibrating like a tuning fork. Tandy figured that a fan in the laboratory had created an infrasound wave, one below the range of human hearing. The vibrations of the sound wave had caused the foil to quiver. Tandy measured the vibrations at 18.9 hertz (cycles per second. Tandy also knew that the human eyeball shakes when exposed to a soundwave of about 18 hertz (Hz). Putting two and two together, he deduced that what he had seen was no ghost; it was simply blurry vision caused by the shaking of his eyeballs. Later, Tandy took his instruments to a famous haunted cellar in Conventry, England, and tested for infrasound there. Sure enough, the instruments registered the existence of an infrasound wave in the cellar that peaked at 18.9 Hz. Another ghost busted!"
